265119 ÷ 87 
The aim is to understand the frequency of 87 in 265119.

Moving on to step 1:
When dividing 2 by 87, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 87

Step 2:
The number 87 fits into 26 0 times, leaving a remainder of 26.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 26, we get 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 87

Going ahead to step 3:
265 divided by 87 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 3.0
Deduct 261 from 265 and we're left with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 87

Going ahead to step 4:
If we divide 41 by 87, we get 0 and a remainder of 41.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 41 after subtracting 0 from 41.
Grab the next digit (1) from the dividend, add it to 41, then carry on: 411 / 87

Advancing to step 5:
When dividing 411 by 87, we get 4 with a remainder of 63.
Use 4 as the next digit of our solution. 
Result so far: 304.0
Subtract 348 from 411 to get 63.
Append the next digit (9) from the dividend to 63 and continue with: 639 / 87

Going ahead to step 6:
The number 87 fits into 639 7 times, leaving a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 3047.0
The remainder is 30 after subtracting 609 from 639.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
When dividing 300 by 87, we get 3 with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 3047.3
Deduct 261 from 300 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 8:
The number 87 fits into 390 4 times, leaving a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 3047.34
Subtract 348 from 390 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
The number 87 fits into 420 4 times, leaving a remainder of 72.
Write down 4 as next digit of the result. 
Result so far: 3047.344
The remainder is 72 after subtracting 348 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 3047.344 with a remainder of 0.0072.
